Abstract

The ferroelectricity of poly(vinylidene fluoride-trifluoroethylene- chlorofluoroethylene) terpolymer films fabricated using Langmuir-Blodgett technology were investigated from 180 to 300 K. The temperature dependences of the remanent polarization and the dielectric response showed a broad peak at ∼270 K, suggesting a ferroelectric phase transition. Unlike perovskite relaxors, a deviation from Merz's law was observed in the relationship between the coercive field and the frequency, which was used to measure the hysteresis for the relaxor terpolymer. The specific ferroelectricity of the relaxor terpolymer is considered to be associated with the distinctive structure and dynamics of its typical molecular conformations.
